WebMonatomic gas. In physics and chemistry, "monatomic" is a combination of the words "mono" and "atomic", and means "single atom ". It is usually applied to gases: a monatomic gas is a gas in which atoms are not bound to each other. Examples at standard conditions of temperature and pressure include all the noble gases ( helium, neon, argon ...

What makes noble gases unique? – How It Works
Noble gas is translated from the German noun Edelgas, first used in 1898 by Hugo Erdmann to indicate their extremely low level of reactivity. The name makes an analogy to the term "noble metals", which also have low reactivity. The noble gases have also been referred to as inert gases, but this label is … Ver mais The noble gases (historically also the inert gases; sometimes referred to as aerogens ) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases … Ver mais The abundances of the noble gases in the universe decrease as their atomic numbers increase. Helium is the most common element in the universe after hydrogen, with a mass fraction of about 24%. Most of the helium in the universe was formed during Big Bang nucleosynthesis Ver mais The color of gas discharge emission depends on several factors, including the following: • discharge parameters (local value of current density Ver mais • Noble gas (data page), for extended tables of physical properties. • Noble metal, for metals that are resistant to corrosion or oxidation. • Inert gas, for any gas that is not reactive under normal circumstances. Ver mais The noble gases have weak interatomic force, and consequently have very low melting and boiling points. They are all monatomic gases under standard conditions, including the … Ver mais The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with … Ver mais Noble gases have very low boiling and melting points, which makes them useful as cryogenic refrigerants. In particular, liquid helium, which boils at 4.2 K (−268.95 °C; −452.11 °F), is used for superconducting magnets, such as those needed in nuclear magnetic resonance imaging Ver mais WebThis chemistry video tutorial provides a basic introduction into the noble gases - the group 18 or group 8A elements.

They are members of group 18, the last group on the periodic table. All of the noble gases occur in the atmosphere. In fact, air is 0.934% argon, while the other group 18 elements are present in much smaller quantities. bitesize learn to type
